Section 2: Hydraulic Set-up Options
Control Stick Functional Checks
Refer to Figure 2-13:
IMPORTANT: Before engaging the tractor's power
take-off, make sure the reservoir is full of hydraulic
oil, the shut-off valve is turned on and that the
hydraulic plumbing is configured correctly for your
tractor's hydraulic flow rate. See "Flow Control
Valve Plumbing" on page 24 for plumbing
requirements.
Solenoid Control Option: The Tractor's hydraulic
control lever and power take-off shaft will need to be
engaged to make control stick functional checks.
Independent Control Option: Only the Tractor's
power take-off shaft will need to be engaged to make
control stick functional checks.
Momentary ON Push Button Checks
IMPORTANT: If included, make sure "Deck Float"
and/or "Deck Motor" push buttons are "OFF" .
Cycle "ARM 1" , "ARM 2" , and "Deck Pivot" cylinders to
ensure they operate properly as follows:
1.
Read and understand hooking-up and unhooking
"Transport Safety Chain" on page 18. Remove
transport safety chain from the latched position and
place loose end on storage hook.
2. Start tractor and adjust 3-point hitch until driveline is
approximately level.

3. Extend and retract hydraulic cylinders as follows:
Solenoid Control
a. Do not engage power take-off for this check.
b. Two hoses for operating "ARM 1" , "ARM 2" , and
"Deck Pivot" cylinders are connected to a duplex
outlet on the tractor. Lock control lever for that
duplex outlet in either "Extend Position" or
"Retract Position" .
c. Refer to Figure 2-13: Press and hold push button
labeled "ARM 1 OUT" momentary. The inboard
parallel arm should start to extend outward. If it
does not move, or moves in the wrong direction
(retracts), you should do one of the following:
•
Change the position of the tractor control lever
from automatic retract to automatic extend or
vice-versa.
•
Reverse hoses at the duplex outlet.
•
Check hydraulic plumbing to and from the
solenoid box to make sure hydraulic hoses are
not plumbed in reversed order.
d. Check hydraulic fluid level in your tractor's
reservoir. If low, add fluid to the system before
continuing. The cylinders and hoses will require
approximately 1 3/4 gallons from the tractor.
